You're right - the QEWD architecture is as you describe, and not that unusual, though I'm not aware of anyone else having implemented such a design with Node.js. I'm not sure there was a good reason for Node's not using something similar, but then again, I'm not really proposing that Node.js should be like QEWD. The fact is I've been able to implement QEWD's architecture using standard Node.js capabilities. So it provides a way of working around the deficiencies of Node that are a direct result of its intentional architecture, if that's what you want to be able to do - best of both worlds.

Not sure I understand your GC questions, sorry?
